Izinto eziwuketshezi1

Ama-molecule edayi ahlakazekayo mancane, ukwakheka kodayi ngaphandle kwamaqembu ancibilika emanzini, ukudaya ngosizo lwe-dispersant, udayi ohlakazekile esixazululo sedayi, ukudaya imicu ye-polyester. I-ejenti ehlakazayo yei-sodium hexametaphosphateiyi-ejenti eyisizayo yokuthuthukisa izakhiwo ezihlakazayo zezinto eziqinile noma eziwuketshezi.

Nge-ionic dispersant, i-disperant encibilikisiwe emanzini ingakwazi ukwenza i-ion enhle nama-ion angalungile, lawa ma-ion akhangiswe ebusweni bezinhlayiya ze-colloid ngamashaji ahlukene, bese kwakheka ungqimba lukagesi oluphindwe kabili ebusweni be-ion, okuholela ekuthuthukisweni okungenzeka. Okwe-non-ionic dispersant, i-disperant incibilika emanzini futhi i-adsorbed ebusweni bezinhlayiyana ze-colloidal, ezizungeze inhlayiya futhi yakha isithiyo esiqinile, ivimbela ukuthintana phakathi kwe-reagent yokusabela kanye nesikhungo sokuphendula.

I-sodium hetaphosphate iyingxenye ye-polyphosphate. Isakhiwo sayo samangqamuzana siyisiyingi, kodwa sinokucushwa kweketango elide eliwumugqa. Ikhangiswe ebusweni bezinhlayiya ngeqembu lokugcina, kuyilapho iketango eliphakathi lingabandakanyi ekubopheni, okunganikeza ukuxoshwa okwengeziwe kwe-electrostatic. I-ionized anion ye-sodium hetaphosphate encibilikisiwe emanzini akhangisiwe endaweni yezinhlayiyana, okukhulise amandla e-electronegativity endaweni yezinhlayiyana. Ngaphezu kwalokho, i-ionized Na + ion ingakhuphula ubukhulu bengqimba kagesi ephindwe kabili, futhii-sodium hexametaphosphateidlala umphumela wokuhlakazeka ngaphansi kwale miphumela emibili.

Yomibili le miphumela izokwandisa amandla aphikisayo phakathi kwezinhlayiya, okuholela ekukhululweni kwamanzi amahhala ahlanganiswe nesakhiwo esihlanganisiwe, ngakho-kei-sodium hexametaphosphatei-dispersant ingadlala indima yokuhlakaza izinhlayiya kanye nezinhlayiya zokugcoba. Inhloso yawo eyinhloko ukunciphisa ukungezwani phakathi kobuso phakathi koketshezi - uketshezi nokuqinile - uketshezi. Ngakhoi-sodium hexametaphosphateI-disperant nayo iyi-surfactant.

Lapho ugaya udayi oqinile, wengezai-sodium hexametaphosphatei-disperant ingasiza ukuchoboza izinhlayiya futhi ivimbele izinhlayiya eziphukile ukuthi zingafinyeleli futhi zigcine ukuhlakazeka kuzinzile. Uketshezi olunamafutha olungancibiliki emanzini ngaphansi kwe-shear high force enyakazayo, lungahlakazwa lube ubuhlalu obuwuketshezi oluncane, luyeke ukunyakazisa, ngaphansi kwesenzo sokungezwani esibonakalayo ngokushesha stratified, bese wengeza i-sodium hetaphosphate dispersant enyakazayo, ingakha i-emulsion ezinzile.
